Application filed October 25. 1923. Serial No. 670.652.

' To all whom. it may concern:

-Be it known that 1, ROBERT F. RUNGE, a citizenof the United States, residing-at Forest Hills, in the county of Queens and 5 State of New York, have invented certain new and useful Improvements in Ball Cages or Retainers for Ball Bearings, of which the following is a specification, reference being had therein to the accompanying drawings. V

This invention relates to ball retaining separators or cages for use in ball bearings and has for an object to provide a strong and eflicient sheet metal device of this character which will have long life in service and which will not unduly wear the balls associated with it in thebearing. The cage is made of two similar drawn or pressed sheet metal rings. These are rovided with recesses or sockets forming ba 1 pockets and are rigidly and permanently connected together. he entire ball engaging surfaces of the walls surrounding each pocket are formed from the face of the blank as distinguished from previously known structures in which the cut edges of the notches in the ring and web contact with the balls Such cut edges unless carefully smoothed have a; tendency to-- scratch and mar the highly polished surfaces of the balls. The drawing operation as I practice t. leaves the pocket surfaces smooth.

In the drawin s forming a part oi this application an il ustrative example of my as improved cage is shown, in which draw- Figure 1 is a rspective View of one of the halves or twin members of the ea c.

Fig. 2 is an elevation looking at this mm to the smile which is engaged by the other half Q1! twin. Fig. 3 is an edge View. gig. 4: is a section of-the completed cage, an Fig. 5 shows a blank prior to the drawing gfrerations.

A awn sheet metal ring is shown comprising a substantially cylindrical portion, 7 and radially disposed lugs or web sections, to 8. The web sections of two of these rings are rigidly and permanently connected together in some suitable manner, rivets, 9, being shown in the illustration passing through suitably formed openings, '10; The aaball pockets, 11, are formed inthe cylindrical portion, 7, of the ring and between the lugs or web sections, 8. The edges of thering .body and the web sections are turned outwardly at the pockets in a substantially continuous flange. The portion, 12, turned up from the body of the ring merges into the portions, 13, turned up fronr the two adjacent web sections, 8. It will be seen that the entire ball engaging surfacesof the walls surrounding these pockets, 11, are formed from the face of the blank. In the illustration they are continuous with the inner face, 14, of the ring or body portion which is also continuous with the face, 15, of the'ring which engages a similar face of its companion ring or twin.

It will be noted that the ball pockets are I above mentioned. This adds to the strength,

lightness and pleasant appearance of the structure WhGIl'ELSSBlIlblBCl for use in a ball bearing and obviates the necessity of spe cially rming this edge other'than to punch out the hole, 18, in the blank.

I claim as my invention: Y 1. A ball cage comprising a pair of sheet 'meial rings each having a cylindrical body portion and radially disposed lugs or we sect-ions, the body portion being recessed between adjacent webs and the body at the region of the recess and adjacent edges of the lugs having turned over edges, such turned over edges forming a continuous flange. .1 3

' 2. A ball cage comprising a pair of similar sheet metal rings formed with radially disposed lugs '01; web sections these being rigidly fastened together, the rings being formed with recesses between the lugs or web sections, the edges of the ring and web sections being turned outwardly at the re-;

cesses.

3. A ball cage comprising a pair of drawn 1y; cylindrical portion carrying radially disward the higs and outwar sheet metal rings each having a substantialdrawn sinuous outline eurvin inwardly to- I ily from the p0%d lugs 01' Web sections, there being ball p0ckets. 10 pockets between these extending into the In testimony whereof, I have afiixed my 5 cylindrical portion, metal of the latter signature hereto.

portion being drawn toward the respective lugs, whereby 'the opposite edge presents a ROBERT F. RUNGE.
